Title: Improvements in or relating to cutting, folding and delivery mechanism
IPC: B41F13/54
Filed: 1943-05-31
Abstract: 564,049. Cutting, folding, and delivery apparatus. GOSS PRINTING PRESS CO., Ltd. May 31, 1943, No. 8691. Convention date, June 3, 1942. [Class 100 (i)] A number of webs W from a rotary printing or other machine are cut, folded and delivered by apparatus which permits of varied products which may comprise two separate products corresponding to different printing formes, or in which these products are associated so as to be delivered as one product, and in each case the products may be folded either once or twice, and may be slit or not to produce narrow products or one wide product. The webs W are first cut by cylinders 12, 14, with impaling pins 18 for transferring the sheets to impaling pins 21 on a cylinder 20 which is fitted with three sets of pins 21, three grippers 22, and three folding blades 24. To produce separate products to be delivered finally to conveyers 39, the cut sheets are folded alternately by the blades 24 into jaws 31 on the two cylinders 30. From the cylinders 30 the once folded products may be folded again by a blade 33 into a jaw 35 on a delivery cylinder 36, or the blade 33 may be silenced and the once folded product taken by grippers 38 on the cylinder 36, a segmental feed roller 43 serving to assist the transfer of the once folded product. The cylinder 36 may be driven at the same speed as the cylinder 30, or at half the speed when the sheets are not collected on cylinder 30, and the delivery cylinder is fitted with a slitting disc or discs 40 which may be put out of action if desired. When the cylinder 20 acts as a collecting cylinder, one cylinder 30 is put out of action and the grippers 22 collect two sheets before the folding blades 24 come into action. Specification 396,486 is referred to.

Title: Improvements in the measurement of alternating potential differences
IPC: G01R19/00
Filed: 1922-03-25
Abstract: 199,483. Moullin, E. B. March 25, 1922. Pressure meters.-A direct-reading voltmeter for alternating electric potentials, and particularly for potentials below 3 volts, comprises a 3-electrode thermionic valve with asymmetrical conductivity between the anode and filament, the potential being applied between terminals AB connected to the grid and filament, and the increase in mean anode current, due to the applied potential and to the curvature of the characteristic of the valve, being measured by a galvanometer G connected between the positive side of the filament and the anode and calibrated to read the applied potential directly. The terminal B may be connected to a fixed point of the variable filament resistance S at a potential of 1.6 volts negative with respect to the negative side of the filament. The anode circuit includes no battery, the potentials of the anode, grid, and filament being all controlled by the resistance S. In calibrating the instrument, the zero of the galvanometer scale is taken at the reading obtained when the terminals A, B are connected together and when the resistance S is adjusted until the potential drop across the filament is about 3.6 volts. Standard conditions are obtained in use by adjusting the resistance S until a zero reading is obtained with the terminals A, B connected together. A high resistance R of the order of 30,000 ohms is included in the anode circuit in order to obtain galvanometer deflections more nearly proportional to the applied potentials, the resistance R decreasing the mean anode potential when the applied potential, and consequently the anode current, increases, and thu spreventing too rapid increases in the mean anode current. A condenser C of the order of 1 microfarad connected in shunt to the galvanometer G and resistance R provides a path of small impedance for the alternating component of the anode current and prevents fluctuations of the anode potential, thus giving readings independent of frequency changes. In a modification, the grid is maintained at the required negative potential by a separate cell between the terminal B and the negative side of the filament.

Title: Improved automatic means for ensuring extension of retractable alighting gear for aircraft
IPC: B64C25/20
Filed: 1938-03-22
Abstract: 494,557. Retractable landing - gear for aircraft. POTEZ, H. C. A. March 22, 1938, No. 8743. Convention date, Feb. 9. [Class 4] A retractable, alighting-gear for aircraft of the kind comprising a swinging leg and a folding strut is provided with means acting after the manner of a compression spring and having its ends attached one to each half of the folding strut in such manner as to tend to straighten the said strut against the action of the retraction mechanism. As applied to a wheel landing gear, Figs. 1 and 3, a strut 3 pivoted to the aircraft at 4, carries a wheel axle at 2, and is braced by a folding strut comprising elements 7, 8 pivoted together at 9 at which point the force for retraction is applied. In the " down " position, element 8 rests against a stop 13. A compression spring or equivalent 12 is arranged between extremities A, B of members 10, 11 respectively mounted on elements 7, 8. In the " down " position the compression force of the spring gives rise to a couple tending to maintain the strut 3 in the extended position and in a position intermediate the " down " and " up " positions, the extending couple has a high value, but in the " up " position, Fig. 3, the couple vanishes or changes. in sign. Thus, during the first stage of extension, the wheel falls under gravity and is; thereafter urged by the device 12 into operative position. The device 12 may take the form of a cylinder 14 having a gland at 16 for the passage of a hollow piston 17 of which the bore is extended by a pipe 19 communicating with a tank 18. The device is pivotally connected to members 10 and 11 by a lug 15 at one end and by journals 21 formed on a cylinder 20 at the other. The cylinder and piston may be filled with liquid and tank 18 contains a gas under pressure, but by suitable modification of gland 16, air alone may be employed, tube 19 or both tube and tank being omitted.

Title: Improvements in or relating to the amplification of cable signals
IPC: H04L25/06
Filed: 1928-03-23
Abstract: 314,122. Symonds, E. O. March 23, 1928. Restoring imperfect signals.-Recording-apparatus for cable telegraphs employing resistancecapacity coupling in the amplifier is provided with a compensating device designed to restore the flat-topped form of the signals. As shown in Fig. 1, the signals are amplified by a series of valves with resistance-capacity coupling, the output valve 11 having the moving coil 17 of the recorder connected to its plate. As the coil moves in response to a received signal of the form shown in the curve 26, Fig. 4, an arm 21 moves from a central neutral contact 19 to a positive or negative contact 20, 18. The grid of a compensating- valve 15 is thus charged positively or negatively through a series resistance 24, a condenser 25 being connected across the grid and filament. The resistance 24 and condsenser 25 are of such values that the charging-curve 28, Fig. 4, for the compensation grid is of the same shape as the falling response curve 27 of the amplifier. The current through the moving coil 17, which is connected between the plates of the valves 11, 15, is thus maintained constant during the duration of the signal, as indicated by the curve 29, Fig. 4. In a modification, the moving coil 17 has two separate windings respectively connected in the plate circuits of the valves 11, 15. in another arrangement, one of the valves of the amplifier is used as the compensating-valve, the moving-coil being connected directly in the plate circuit of the last valve. When a filter circuit is used in the amplifier for excluding currents of higher frequency than the signals, a corresponding network is arranged in the grid circuit of the compensating valve. A transformer may couple the cable to the amplifier, and a shaping circuit may be interposed.

Abstract: 442,333. Television. RADIOAKT.- GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. March 27, 1935. No. 9521. Convention date, March 31, 1934. [Class 40 (iii)] The synchronizing signal consists of an oscillation with a frequency equal to a multiple of the line frequency, and is weakened or interrupted for a brief period to form the image-change signal. The synchronizing frequency is above audibility and modulates the ultra-short wave carrying accompanying sound. For a brief period at each imagechange, a cut-out 15<1> disconnects from the transmitter 15 for the sound the apparatus 6, which modulates the carrier-wave for the sound with the synchronizing signal. At the receiver, Fig. 2, the tuning of the television and sound receivers is so coupled that, when the sound receiver is correctly adjusted, the television receiver is also in correct adjustment. A common local oscillator 16 is used for both receivers. The synchronizing frequency is applied to a special rectifier 29, the direct current from which synchronizes the image-change relaxation oscillator at a terminal 32. The synchronizing oscillation controls the line-frequency relaxation oscillator directly at a terminal 28.
